PLOW-STOCK.

SPECIFICATION forming part of Letters Patent No. 638,399, dated December 5, 1899.

Application filed July 29, 1399. Serial No; 725,532. (No model.)

T0 at whom it may concern:

Be it known that I, JAMES W. PERRY, a citizen of the United States, residing at Monetta, in the county of Saluda and State of South Carolina, have invented a new and useful Plow, of which the following is a specification.

This invention relates to plows or cultivators, and more particularly to the stock or standard; and the object of the sameis to provide means of novel form for varying the pitch of the plow or cultivator to regulate its depth of penetration in the soil, the adjustment being regulable while the plow is in use by a change of position of readily-accessible parts, or the degree of penetration may be fixed before the plow is used, and thereby accomm odate the cultivation of soils having different characteristics and also compensate for working plants or growths requiring a variation in the depth of penetration of the plow or cultivator.

The invention consists, essentially, of a plow-beam provided with a forwardly-projecting pendent brace-arm, to which is pivotally attached a plow or cultivator standard of forked form and embracing opposite sides of the said beam, the upper portion of the standard being attached to a yielding keeper carrying a depending stud or pin to enter either one of a plurality of recesses in the upper adjacent edge portion of the beam to hold the standard in different angular positions of adj ustment relatively to the said beam.

The invention further consists of the construction and arrangement of the parts in detail, which will be more fully hereinafter described and claimed.

In the accompanying drawings, Figure l is a perspective view of a plow embodying the invention. Fig. 2 is a longitudinal vertical section of a portion of the improved attachment, a part of the plow-beam being broken away to show the'operation of the locking device.

Similar numerals of reference are employed to indicate corresponding parts in the views.

The numeral 1 designates a plow-beam having handles 2 and a clevis 3, the said beam being of any preferred form. To the under side or edge of the rear portion of the beam 1 the upper end of a forwardly-projecting pendent brace-arm at is secured and the free terminal of the said arm is pivotally embraced by a forked standard 5. The opposite members of the said standard are contracted or drawn nearer To each other adjacent their lower ends and united by a suitable interposed space block 6, located between the lower portions of said members, and to this block a plow or cultivator 7 is attached in any suitable manner. An ordinary shovel-plow is shown as applied to the standard; but it will be understood that any plow might be equally well attached or used in place of that shown. The upper portion 8 of each of the members of the standard are spread apart sufficiently to freely or movably embrace the opposite sides of the beam 1 and are connected by a continuous web 9, which is located above and close to the upper surface or edge of the said beam. The web 9 has a rear extension IO, and from the opposite edges of the latter short posts 11 rise vertically. Between the upper ends of the said posts the one terminal of a yielding keeper 12 is permanently secured, the said keeper in advance of the posts being looped, and thus provided with a lower return-bend 13, which is continued rearwardly between the said posts and has an upstanding angular extension 14, which is continuous, with a rearwardly-projecting horizontally-disposed grip 15. The said grip 15 is disposed within convenient reaching distance from the handles 2 or the operator from his position relatively to the said handles. Extending downwardly from about the central portion of the return-bend 13 is a stud or pin 16, which is adapted to be received in either one of a series of pin or stud sockets 17, formed in the upper adjacent portion of the beam 1 and continued through a wearplate 18, fastened to the said beam thereover. The under edge of the beam 1, immediately below the pin or stud sockets 17, is formed with a concaved recess 19, and extending transversely across the members of the standard adjacent the location of the said recess 19' is a guide-pin 20, which causes the said standard to move in a regular arc of a circle in its adjustment on the fulcrum instituted by the pivotal connection of the terminal of the brace-arm 4 with the said standard.

To change the adjustment of the standard, an upward pressure is applied to the returnbend 13 of the keeper through the grip 15 to release the pin or stud 16 .from the pin or stud socket with which it may have been in engagement, and the said pin or stud is held clear of the plate 18 while the said standard is moved forwardly or rearwardly in accordance with the angle of adjustment desired, when said pin or stud is liberated and permitted to enter the proper pin or stud socket. The resiliency of the keeper 12 is sufficiently strong to hold the pin or stud 16 in either one of the pin or stud sockets 17 against accidental displacement or disconnection, and by eX- tending the return-bend rearwardly between the posts 11 lateral play or resilient twist of said bend is prevented, and the pin or stud carried thereby is always held in engageable position with the said pin or stud sockets when moved over the latter.

The improved device can be easily applied to plows now in use without involving material expense, particularly when considered comparatively with the increased advantages that accrue from the adjustment of the standard and the means thereby imparted for varying the penetration of the plow or cultivator.

To accommodate various applications, changes in the form, proportions, size, and minor details of construction can be resorted to without departing from the spirit or sacrificing any of the advantages thereof.

Having thus described the invention, what is claimed as new is- 1. In a plow, the combination of a beam, a standard pivotally connected to the beam, and a yielding keeper attached to the upper portion of the standard and having a locking device adapted to coincide with relative devices in the said beam.

2. In a plow, the combination of a beam, a

standard pivotally connected thereto, ayielding keeper attached to the upper portion of the said standard, and a depending pin or stud carried by a portion of the said keeper and adapted to be held in respective devices on the beam.

3. In a plow, the combination of a beam, having a line of sockets in the upper edge thereof, a standard pivotally connected to the said beam, a yielding keeper attached to the upper portion of the said standard, and apin or stud depending from a portion of the said keeper and adapted to enter the said sockets and hold the standard at different angles of adjustment.

4.. In a plow, the combination of a beam having a concaved recess in the under edge thereof, a standard pivotally connected to the said beam, a cross-guide attached to parts of the standard to coact with the said recess in the beam, and a yielding keeper attached to the upper portion of the standard and hav ing alocking element adapted to be received in relative devices on the beam.

5. In a plow, the combination of a beam, having a series of sockets in the upper edge thereof, a standard pivotally connected to said beam, and embracing opposite sides and the top portion of the latter, the said standard carrying upper posts, a yielding keeper having one member rigidly secured between the posts and another member movably extending through the posts and provided with a grip, and a .pin or stud carried by the member of the keeper movably extcndingthrough the posts and adapted to engage the said sockets in the beam.

6. In a plow, the combination of a beam,

having upstanding projections at the upper portion thereof, a yielding keeper in part secured to and also partially movably between the said projections and provided with a rear grip, said keeper being attached to the standard, and a pin or stud carried by the keeper and adapted to adj ustably engage receptive devices in the beam.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.
